Lateral Femoral Cutaneous Nerve

  • Provides sensation to the lateral thigh.
  • Originates from the lumbar plexus.
  • Runs on the surface of the iliacus muscle and enters the thigh by passing under the inguinal ligament before piercing the fascia lata
  • Location is variable. 
  • Average medial distance from the ASIS is 20.4 millimeters, with a range of three to forty-six millimeters. In no specimen did the nerve pass lateral to the ASIS. The lateral femoral cutaneous nerve lies anterior to the iliopsoas muscle. (Hospodar PP, JOT 1999 Jan;13(1):17-9)
